Apple users are complaining of faults with the company's iPad Pro tablet, reporting that the device shuts down when plugged into charge and requires a hard reset to revive.
Device owners claim only a force reboot - holding down the home and power button simultaneously - will revive the frozen tablet.
"When I connect my iPad Pro to the charger for more than an hour, it goes dead. It takes multiple hard resets to bring it back to life," one user wrote.
"At night it was down to 40 per cent so I charged it and went to bed. When I woke up it was 'dead.' It wouldn't wake up. I needed to perform a hard reset to get it to come to life," another user said.
"Worked on it for a couple of hours and had to run an errand. Plugged it back in as I was going to need a full charge later that day. Came back to it, same thing. Dead. I needed to perform a hard reset to get it to turn on."
Another user said the issue had occurred every night for the three days he had owned the device.
"Every night I charged it, it was off in the morning. Needed a hard reset," he wrote.
"Erased all content and settings last night, this morning I have no issue. Sucks that this is happening, but at least it seems fixable."
Some users reported that the issue resolved itself after they restored the device from iTunes. Others said reinstalling the iOS 9.2 beta fixed the problem.
Apple has been contacted for comment.
The company launched the iPad Pro, the largest version of its popular tablet, in September.
It is marketing the 12.9in device as a replacement for notebooks and Microsoft's Surface, with a keypad that attaches to the iPad via a magnetic connector that handles power and data. The tablet also comes with a stylus.
The iPad Pro became available this month, retailing for between $1249 to to $1699 in Australia.
